GUADALUPE prefixes in area code 805

NANPA records 5 assigned NXX blocks to rate center GUADALUPE in area code 805, 0.6% of the 786 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 5 holders hold those blocks, the largest being CHARTER IP ENABLED SERVICES, LLC (1), LEVEL 3 TELECOM OF CALIFORNIA, LP - CA (1), FRONTIER CALIFORNIA INC. (1). The earliest assignment on record here is 2007-03-30 and the most recent 2022-05-20. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area code 820 – overlay codes cover the same geography, so a rate center is served by all of them.
